Abstract

A bone fragment manipulating tool with reversible pulling mechanism generally comprises an elongated shaft defining a shaft diameter and a drill bit at a distal end. An elongated tubular housing having a housing diameter greater than the shaft diameter encloses the shaft. As the shaft axially retracts in the direction of the tubular housing, a radially protruding structure secures the shaft to a chipped fragment of the bone. The tool then manipulates the fragments to their proper orientations. A method of manipulating a fragment of a fractured bone using a tool generally comprises drilling through the bone, deploying a radially protruding structure to secure the shaft to a chipped fragment, manipulating the chipped fragment to a proper orientation with respect to a primary fragment such that the fragments are aligned and joined, undeploying the radially protruding structure, and removing the tool in a locked, slender configuration from the bone.
